[PATCH v6 24/25] arm64: kernel: Respect the hierarchical CPU topology in DT for PSCI

From: Ulf Hansson
Date: Wed Mar 14 2018 - 13:00:48 EST


To let the PSCI driver to parse the CPU topology in DT, as to create CPU PM
domains in case the hierarchical layout is used, let's call
psci_dt_topology_init() from the existing topology_init() subsys_initcall.
